Why does a space shuttle carry hydrogen and why do they keep hydrogen and oxegen it in its liquid?
The space shuttle carries oxygen for two reasons: to allow the crew to breathe and to act as an oxidizer for its hydrogen fuel.

526,000 gallons of super-chilled liquid oxygen and liquid hydrogen propellant.
The space shuttle uses liquid nitrogen and liquid oxygen as fuel. Generally a sufficient quantity of fuel is carried but if need be re-fuelling can be done in space.
There is no oxygen or air in space so the shuttle has to have its own supply.
The amount of oxygen required for combustion is more than the air alone can provide. Especially when the air is getting thinner with altitude and eventually the rocket leaves the atmosphere.
Pratically the entire interior volume of the lower stages of rockets is fuel. This is why they have to be large: to hold enough fuel to accelerate the upper stages and carry them into orbit. The fuel may be liquid or solid. The space shuttle main engines used liquid oxygen and liquid hydrogen, which was heated back to a gaseous state just before it burned in the rocket engines.
The Space Shuttle's External Tank carries 383,000 gallons of liquid hydrogen and 143,000 gallons of liquid oxygen to power the Space Shuttle Main Engines. The SSMEs burn for about 8.5 minutes (510 seconds), which means they consuming about 751 gallons of hydrogen per second and 280 gallons of oxygen per second, or about 1031 gallons of propellant overall per second. As an aside, the Solid Rocket Boosters each carry 1,000,000 pounds of solid propellant (both fuel and oxidizer are combined) and burn for about two minutes. So, that equates to about 16,667 pounds of propellant per second for the SRBs.

Have you SEEN the price of gasoline lately....Just kidding-- Rockets fuels are rated by Specific Impulse, a measure of how fast the explosion travels when it shoots out the back. Gasoline is good as a fuel, but not as good as many others. The space shuttle uses hydrogen and oxygen.
Actually Hydrogen is not normally transported as a liquid because in is considered far too dangerous, hydrogen is transported in high pressure gas cylinders, packs of cylinders (10 or more in a secure steel frame) or on specially built bulk high pressure cylinder trailers, always in gas form. Only on very rare occaisions is hydrogen transported as liquid, one example would be the Space Shuttle which carries liquid hydrogen as part of its fuel load.
The Shuttle can also carry a 65,000 payload.
